谷歌地图API V2不工作(Google Maps API v2 not working)

我想建立使用谷歌地图API版本的应用程序，但事情是，应用一直给我力量关闭虽然我遵循了所有需要的指令。

这是Android的一部分

import android.support.v4.app.FragmentActivity;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;

public class GPSonMap extends FragmentActivity{

 MapView map;
 MapController controller;
 LocationManager locationManager;
 LocationListener listener;
 PendingIntent pendingIntent ;
 Criteria criteria;
 MapOverlay overlay;


@Override
public void onCreate(Bundle onsaved)
{
    super.onCreate(onsaved);
    setContentView(R.layout.map);
    Log.d("", "entered");


    map = (MapView)findViewById(R.id.mapView);
    }

这里是XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MapsActivity" >

<fragment

    class="com.google.android.gms.maps.SupportMapFragment"
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
/>

</RelativeLayout>

另外一个问题，我面对的是，当我尝试
import com.google.android.gms.maps.MapFragment; 它给出了它不识别包的名称是一个错误com.google.android.gms所以我甚至不能使用的GoogleMap或MapFragment例如。

因此，没有人有任何解决这些问题2？

Answer 1:

想必，你还没有加入到谷歌Play服务库项目的引用您的应用项目。 见的谷歌Play服务SDK文档 ，特别是标题为“要建立一个项目，使用谷歌Play服务SDK”。

Answer 2:

如何显示经由谷歌Android地图API V2 GOOGLE MAP。

请注意，所有2箱子设置谷歌播放服务和清单文件，包括一些权限和API密钥是必需的。

1.显示谷歌地图中（支持）片段。

main.xml中

<?xml version="1.0" encoding="utf-8"?>

<!-- This can go anywhere in your layout (see other demos for some examples). -->
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"/>

MainActivity.java

/**
 * This shows how to create a simple activity with a map and a marker on the map.
 * <p>
 * Notice how we deal with the possibility that the Google Play services APK is not
 * installed/enabled/updated on a user's device.
 */
public class BasicMapActivity extends android.support.v4.app.FragmentActivity {
    /**
     * Note that this may be null if the Google Play services APK is not available.
     */
    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        setUpMapIfNeeded();
    }

    @Override
    protected void onResume() {
        super.onResume();
        setUpMapIfNeeded();
    }

    /**
     * Sets up the map if it is possible to do so (i.e., the Google Play services APK is correctly
     * installed) and the map has not already been instantiated.. This will ensure that we only ever
     * call {@link #setUpMap()} once when {@link #mMap} is not null.
     * <p>
     * If it isn't installed {@link SupportMapFragment} (and
     * {@link com.google.android.gms.maps.MapView
     * MapView}) will show a prompt for the user to install/update the Google Play services APK on
     * their device.
     * <p>
     * A user can return to this Activity after following the prompt and correctly
     * installing/updating/enabling the Google Play services. Since the Activity may not have been
     * completely destroyed during this process (it is likely that it would only be stopped or
     * paused), {@link #onCreate(Bundle)} may not be called again so we should call this method in
     * {@link #onResume()} to guarantee that it will be called.
     */
    private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the map.
        if (mMap == null) {
            // Try to obtain the map from the SupportMapFragment.
            mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();
            // Check if we were successful in obtaining the map.
            if (mMap != null) {
                setUpMap();
            }
        }
    }

    /**
     * This is where we can add markers or lines, add listeners or move the camera. In this case, we
     * just add a marker near Africa.
     * <p>
     * This should only be called once and when we are sure that {@link #mMap} is not null.
     */
    private void setUpMap() {
        mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
    }
}

2.显示MapView类中（支援）片段。

main.xml中

<?xml version="1.0" encoding="utf-8"?>

<!-- This can go anywhere in your layout. -->
<com.google.android.gms.maps.MapView xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"/>

MainActivity.java

/**
 * This shows how to create a simple activity with a raw MapView and add a marker to it. This
 * requires forwarding all the important lifecycle methods onto MapView.
 */
public class RawMapViewDemoActivity extends android.support.v4.app.FragmentActivity {
    private MapView mMapView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mMapView = (MapView) findViewById(R.id.map);
        mMapView.onCreate(savedInstanceState);


    }

    @Override
    protected void onResume() {
        super.onResume();
        mMapView.onResume();


    }



    @Override
    protected void onPause() {
        mMapView.onPause();
        super.onPause();
    }

    @Override
    protected void onDestroy() {
        mMapView.onDestroy();
        super.onDestroy();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mMapView.onLowMemory();
    }


}

Answer 3:

我发现你在你的代码错过了几件事情。

答1：您的GPSonMAP.java必须修改如下图所示;

public class GPSonMap extends android.support.v4.app.FragmentActivity{
 GoogleMap googlemap;  // "MapView map;" is wrong
 //MapController controller;  ==> it was depreciated.
 LocationManager locationManager;
 LocationListener listener;
 PendingIntent pendingIntent ;
 Criteria criteria;
 //MapOverlay overlay; ==> it was depreciated.
 SupportMapFragment fm; // add this


@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
        Log.d("", "entered");


    //map = (MapView)findViewById(R.id.mapView); ==> delete it.

     fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapView);
     googleMap = fm.getMap();
    }


}

修改上述， 按“Ctrl + SHFT +（字母）O”和一些所需的类之后将被导入。

答2：在布局XML文件必须进行修改像下面;

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".GPSonMap" >

您的MainActivity不是MapsActivity，但GPSonMap。

答3：你的清单文件并不在清单文件中描述的包名称相匹配的包名。 请同一个匹配软件包的名称。

修改“com.example.example”你的包名。

复制和粘贴一些代码后， 必须至少检查包名和类名。

Answer 4:

我有这个问题，是在浪费时间（超过1.5天头发拉挫折）。 然后我看着一个YouTube视频是在做一个无聊穿行的指示加入谷歌Play服务的应用程序。 那么，从他们使用的Eclipse的“检查更新” SDK Manager中添加SDK后，该视频。 那个小片神奇的走了出去，并下载一个jar文件，该SDK管理器不会做！ 他们真的需要它添加到指令和救人的无奈。 我很想刚刚从我的应用程序中删除谷歌地图。 我用1.0和我需要更新到2.0或沟地图。
